Re: can't communicate with fenced -1

Hi,
the problem of my cluster is that it start-up weel but after two days the problem that I have described is running, and this problem gets solved if the two machines are rebooted at the same time.

Thanks

Hi,

We have two RHEL5.1 boxes installed sharing a
single iscsi emc2 SAN, whitout fence devices. System is configured


as a high-availability system of xen guest. 

One of the most repeating problems are fence_tool related.

Sometimes this problem gets solved if the two machines are rebooted at



the same time. But in the current HA configuration, I cannot guarantee
two systems will be rebooted at the same time for every problem we
face. This is my config file:

Hi

 

I configured a two node cluster with no fence device on RHEL5.1.

The cluster started and stopped with no issues. The only difference that I see is that I have used FQDN in my cluster.conf

 

i.e., <clusternode name="yoda2.gsr.com" nodeid="1" votes="1">

 

Check your /etc/hosts if it has the FQDN in it.

 

Thanks
